(Cl. 10S-1) 6 Claims.

YThis vinvention rela-tes to improvements ln mountings for fluid pumpsand has among other objects to provide a simplified and improved meansfor mounting a plurality of fluid pumps on the end of the casing of adrive ino-tor for the pumps and affording a simplified means forsupplying uid to and conducting fluid from said pumps.

A more specic object of my invention is to provide a novel andsimpliiied mounting for a purality of uid pumps arranged to mount saidpumps on the end of the casing of a drive motor therefor, which is soconstructed and arranged that suction and pressure iiuid conduits may beset in said mounting and register with the suction and pressure ports ofsaid pumps, so said pumps may readily be connected to said mounting andsaid suction and pressure connections withoutthe use of lindividual`external piping to said pumps, and enabling the pump mounting tO beconstructed of one type of `metal and the lluid conducting means to beconstructed from another material less susceptible to porousness 4andblow holes and resultant leakages than the mounting for said pumps.

An application Serial No. 591,896, `filedby me on May 4, 1945, relatesvto a mounting for a plurality of fluid pumps on the end of the `casingof the drive motor for the pumps. My present application isacontinuation in part of application Serial No, 591,896 and differstherefrom 'in that in my present application the suction and pressure`iiuid connections for the pumps are separate from the `pump mountingand the vpump mounting i`s so constructed and arranged that these vfluidconnections may be set therein and held in place by the pumps, whensecured 'to the mounting.

These and vother objects :of my invention Will appear from time to timeas the following specification proceeds and with reference to the accompanying drawings wherein:

Figure, l is an end view of a pump `mounting constructed in accordancewith my invention, with several of the pumps removed and with certainparts of the suction manifold broken away and shown inJsection;

Figure 2 is a fragmentary sectional View taken substantially along line`2--2 of Figure l;

Figure 3 is a fragmentary sectional View taken substantially along line3-3 of Figure l;

Figure 4 is an enlarged detail fragmentary sectional view showingcertain details ofthe mounting of one of the pressure fittings in thepump mounting; and

Figure 5 is a detail fragmentary sectional view 'showingcertaindetailsof the'drive to one of the pumps and the mounting of said pump on thepump mounting.

In the drawings an Aelectric motor Ii! of a well 'known form `is shownas affording a source of` power for driving aplurality of fluid pumps II, I I. Said motor has an armature shaft I2 which extends from one endof an end plate 'I3 of a casing I4 of said motor (see Figure 2). Saidarmature shaft extendsthrough an inner plate I5 of a gear housing andpump mounting I6 abutting said end plate and suitably secured thereto,and within an inner portion I'I of said housing, and has a motor pinionI9 splined thereon, within said housing. Said housing and pump mountingmay be `cast from a suitable-material such as steel. End thrust of saidarmature shaft is taken up by a thrust ball bearing 2l) mounted on thehub of said mftor pinion and engaging an annular stationary part of saidinner portion of said housing with its outer race.

The motor pinion I9 .meshes with a plurality Of spur `gears 23, 23. Eachof said spur gears forms a drive means for a fluid pump l I and has ahub projecting from each side thereof (see Figures V3 and 5). Said hubsare journaled On ball bearings 24, 24, the inner bearing being mountedin the inner plate I5 and the outer bearing being mounted within thehousing part I6.

The drive connection from each spur gear '23 to the associated pump I Iincludes a shaft 2'5 mounted Within the hub of each spur gear (seeFigure 3). The outer end of said shaft is slotted and the slottedportion thereof forms a substantially rectangular socket 26 adapted tobe engaged with a corresponding projecting end 21 of a pump drive shaft29 (see Figure 3). The gear housing I5 has a plurality of annularoutwardly projecting portions 3l), 39, which project outwardly from thebearings 24, 24. Said annular projecting portions are concentric withthe axes of rotation of the spur gears 23, 23 and are adapted to havethe pump drive shafts 29, 29 extend therethrough. Said annularprojecting portions terminate into iiat outer plate portions 3|, 32extending outwardly therefrom and having plane finished outer surfacesadapted to be abutted by plane finished inner surfaces of the pumps II,II. The outer sides of said bosses are annularly recessed to receive anannular inwardly projecting flange 33 of a pump I I, to register thedrive shaft 29 of said pump with the shaft 2,5,

The pumps II, II are herein shown as being well known forms of slidingvane pumps, and each includes a casing 34 having the shaft 29 journaledtherein adjacent its ends, which shaft has a rotor 35 of said pumpsplined thereon. An outer head 36 closes the outer end of said casingand is secured thereto as by studs and nuts 3l, 3l. The inner portion ofsaid casing, abutting the housing i6, is of a iianged formation andabuts the outer plane finished surface of the plate portions 3|, 32 ofsaid housing I6, and is secured thereto by means of studs and nuts 39,39 extending through 1 said flanged portion of said casing and threadedin said housing. Said casing 34 has a suction port 4i! leading thereinin the direction of the axis of said pump and opening through theflanged inner portion thereof, for supplying iiuid to said pump. Saidcasing also has a pressure port 4I leading therefrom in the direction ofthe axis of said pump and opening through the iianged inner portion ofsaid housing.

The outer central part of the housing I6 between the pumps II, II andplate portions 3I, 32 for each set of said pumps, is recessed, asindicated by reference character 42 in Figure 3, to receive a suctionmanifold 43 for supplying fluid under pressure to all of the pumps II, II. Said suction manifold may be made of a non-porous metal, lesssusceptible to blow holes and porosity than said housing, and as hereinshown, includes a fluid conduit 44 anged at its outer end and extendingbetween said plate portions and having an ear 45 extending from its endopposite said anged end, between said plate portions. Said ear abuts anouter face of said recessed portion 42 and is secured thereto as by astud and nut 46. Said suction manifold is likewise provided withlaterally extending apertured iiuid outlet portions 41, 41 extending inopposite directions from the central portion thereof and havingapertured portions 49, 49 opening to the outer side thereof in thedirection of the axes of rotation of the pumps I I, I I. One of saidapertured portions is provided for each pump II and the outer facesthereof are nished and are adapted to abut the inner finished faces ofthe pumps II, II and register with the suction ports 40, 4B of saidpumps, to supply fluid under pressure thereto. Suitable packingindicated by reference character 50 may be provided to prevent leakageof iiuid between the iinished inner face of each pump and its associatedapertured portion of said manifold,

The housing IE is also provided with a plurality of pockets I, 5Ibetween the outer plate portions 3I, 32. Each of said pockets opens tothe outer side of said housing and has a shouldered portion 52 openingto the outer side of said hous ing. Each of said shouldered portions isadapt-ed to receive a anged portion 53 of a pressure tting 54, whichtting is adapted to register with the pressure port of an associatedpump I I, when said pump is mounted on the end of said housing. Saidpressure fitting is herein shown as being in the form of an elbow hangedat one end and may be of a diiTerent material than said housing, whichwill be less susceptible to blow holes and porosity than said housing.

The outer side of the flanged portion 53 of the fitting 54 is finishedand is adapted to be abutted by the inner finished surface of theflanged poi'- tion of an associated pump I I. Said fitting is held inposition in the pocket 5I by engagement with said pump, when said pumpis secured to the plane flnished surface of the housing I6. Suitablepacking indicated generally by reference character 55 may be providedbetween said anged portion of said fitting and the finished surface ofsaid pump, to prevent the leakage -of fiuid during operation of saidpump,

It may be seen from the foregoing that a simplied pump mounting has beenprovided which forms a housing for the gearing for driving a pluralityof iiuid pumps and which has outer plane surfaces adapted to be abuttedby corresponding surfaces of said pumps, and adapted to have said pumpssecured thereto. It may also be seen that said pump mounting is soarranged that a single suction manifold may be detachably mountedtherein for supplying uid to all of said pumps, and a simple separatepressure fitting for each pump may be detachably mounted therein andheld in position therein by the associated pump, for conducting fluidtherefrom. It may further be seen that said pump mounting permits theuse of a simplified form of fduid conducting means for supplying fluidto and conducting fluid from the pumps, which may be made from adifferent material than the housing and mounting for said pumps, topermit the use of a metal which may be porous for the housing, and topermit the use of a non-porous material for the fitting and fluidconduits for the pumps, which mounting is so arranged that the pumps maybe mounted thereon or detached therefrom and connected to theirrespective uid connections with a minimum amount of time and effort, andwhich mounting also eliminates all separate external piping connectionsfor each pump.

While I have herein shown and described one form in which my inventionmay be embodied, it will be understood that the construction thereof andthe arrangement of the various parts may be altered without departingfrom the spirit and scope thereof. Furthermore, I do not wish to beconstrued as limiting my invention to the specific embodimentillustrated, excepting as it may be limited in the appended claims.
